The invention discloses a technique for generating a calibrated measurement for an image of an object. The technique discloses receiving at least two input images of the object; performing image standardization process on the at least two input images in order to generate a first set of oriented images; calibrating the first set of oriented images; performing plotting of a plurality of landmark points on the second oriented image after calibration; performing linear measurement process on the second oriented image to obtain linear measurement values; performing transformation of the linear measurement values for the second oriented image into a linear measurement values for a third image of the object based on at least one already obtained calibration factor obtained during a training phase; and computing angular and ratio measurements equivalent to measurements of the third image based on the transformation performed to generate a calibrated measurement of the third image.
